Yes, although I agree with what David Richard's said about the 009 car, that kind of unplanned situation mid-race is very difficult to adapt too because your driver rotation needs to be adapted mid-race and it's luck of the draw as to when it happens whether your drivers will go through a dangerous period of fatigue.
Even as a die hard Aston fan I accept that accident was utterly Hall's fault, and agree that giving a penalty was a fair outcome, but I do think the nature of the penalty the ACO gave was irresponsible.
I did a 24 hour kart race where we lost 2 drivers (one got stomach sickness, one injured in a crash in the twilight). We where lucky to have 4 drivers and a qualified reserve, I consider drivers to be as much a spare part as any other part on the kart. I do wonder why teams enter 3 driver cars, and whilst I agree with Richards, I do think all the teams should look at this - perhaps even the ACO should allow a floating reserve driver for each team.
